The use of a half-cut architecture helps to minimize losses and improve performance under partial shading - which is particularly important in residential buildings with chimneys, skylights, or installations on multiple roof sections. Thanks to features common in modern modules (e.g., a denser grid of connections in the cells), the panels are better able to withstand micro-cracks and long-term operational loads. In practice, the TS-BW60 series stands out for its ability to combine **good efficiency in a compact format** with **stable performance at high temperatures**, which translates into more predictable summer performance. An additional advantage is **a robust construction with tempered glass and anodized frame**, which makes safe installation on roofs and in smaller commercial installations easier. This is a series for investors who expect **reliable performance in Polish conditions** and want to minimize the risk of reduced production in challenging locations. ## Notable figures - At 21.1% efficiency, this panel is on par with typical \*\*PERC 450-500W\*\* modules - Power density of 210.8 W/m² matches the \*\*PERC 450-500W\*\* median - At -0.33%/°C, hot weather performance is typical for \*\*PERC 450-500W\*\* panels - Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof - Ranked #9586 out of 14005 panels for efficiency in the database ## Questions ### Are Sunova TS-BW60 panels still available for purchase? The Sunova TS-BW60 series has been discontinued from current production, so availability is now limited to remaining distributor stock. If you're expanding an existing installation with the same modules, it's worth acting quickly, since the manufacturer will not resume production of this specific series once stock runs out. For new projects, check Sunova's current product lineup instead. ### What warranty comes with Sunova TS-BW60 panels? The manufacturer offers a 15-year product warranty covering material and workmanship defects, plus a 25-year power performance warranty. This means the module should still deliver a guaranteed percentage of its original output after a quarter century of use. Note that Sunova is not a Tier 1 manufacturer, which may be worth considering when assessing long-term company stability. ### How does the bifacial design of the TS-BW60 differ from a standard one-sided panel? The TS-BW60 is a bifacial module, meaning it also generates power from its rear side using light reflected off the ground, roof, or mounting structure. This provides an extra yield boost, especially over light-colored surfaces or in ground-mounted systems with clearance beneath the panel. On typical pitched roofs with minimal rear ventilation gap, the bifacial gain is less pronounced than in ground-mount installations. ### How does half-cut cell technology in the TS-BW60 handle partial shading? Splitting cells into half-cells reduces power loss when part of the panel is shaded, for example by a chimney, antenna, or nearby building. This architecture means shading on one half of the module doesn't shut down the entire panel, only lowers output proportionally to the shaded area. That's a real advantage on residential roofs with complex geometry and multiple roof planes. ### How much energy can I expect from a 460 Wp Sunova TS-BW60 panel? The 460 Wp maximum power rating delivers high power density in a compact module format, which is useful when roof space is limited. Under typical Polish irradiance conditions, a single panel can generate roughly 400 to 500 kWh per year, depending on tilt angle, orientation, and local shading. PERC cells also help maintain stable output during summer heat. ### Do TS-BW60 panels perform well in Poland's climate and cold temperatures? Yes, the PERC cells used in the TS-BW60 have a favorable temperature coefficient, so the panel loses less power during summer heat and can actually perform more efficiently in cooler spring and autumn conditions than in peak summer. Tempered glass and an anodized frame provide durability against snow and wind loads typical of the Polish climate. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/thornova-ts-bw60-445-460-transparent-white-mesh-backsheet-4b4d7a83e879.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +3.7 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +3.6 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +3.4 pp, +5 yr warranty | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.4 pp, +5 yr warranty | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +3.4 pp, +5 yr warranty | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | Cooler, +3.4 pp, +5 yr warranty | | [Sunova TS-BB60(445)](https://comparepv.com/panel/sunova-ts-bb60-445) | 445 W | -10 W, -0.5 pp | | [Sunova TS-BG60(450)](https://comparepv.com/panel/sunova-ts-bg60-450) | 450 W | Heavier, -0.2 pp, +5 yr warranty | | [Sunova TS-BG60(460)](https://comparepv.com/panel/sunova-ts-bg60-460) | 460 W | Heavier, +0.2 pp, +5 yr warranty | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +105 W, cooler, +3.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +100 W, cooler, +3.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +95 W, lighter, +3.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +85 W, cooler, +3.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +85 W, cooler, +3.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | +90 W, cooler, +3.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | +90 W, cooler, +3.1 pp | --- Source: https://comparepv.com/panel/sunova-ts-bw60-455 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
